Management of acute post-operative hemorrhage following partial nephrectomy with renal artery embolization

Hemorrhage after robotic-assisted partial nephrectomy (RAPN) is uncommon but can cause significant morbidity. We present a case of acute hemorrhage isolated to the collecting system that was managed with renal artery embolization (RAE). A 76-year-old male developed sudden onset transfusion-dependent hematuria and hypotension following uncomplicated RAPN. He had no signs of intra-abdominal bleeding and his hypotension was responsive to volume resuscitation. Renal angiography identified a segmental artery with extravasation into the collecting system. RAE eliminated the patient's hematuria, the need for further transfusion, and allowed preservation of renal function. RAE is a viable option for collecting system hemorrhage following RAPN.
